• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tai nang ((ma hoi) OR (mai hoi)). hieu va cac xuc va hanh ((va qua) OR (va quang)) su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tai nang ((ma hoi) OR (mai hoi)). hieu va cac xuc va hanh ((va qua) or (va quang)) su".
